Question

Explain the process of protein synthesis from processed m-RNA.

Answer 1

From the processed mRNA translation is carried out step by step.

• First codon(3 base pair combination) of mRNA strand attaches to a ribosome.
• tRNA carrying a specific amino acid , approaches ribosome.
• Enzyme helps tRNA anti-codon to pair with codon on mRNA.
• tRNA remains with amino acid attached to it.
• Next codon on mRNA slides along ribosome. Steps of adding the specific amino acid continue till the formation of the polypeptide chain.
